Many-body mobility edge in quantum sun models

Pawlik, Konrad (avtor), Sierant, Piotr (avtor), Vidmar, Lev (avtor), Zakrzewski, Jakub (avtor)

The quantum sun model is an interacting model that exhibits sharp signatures of ergodicity breaking phase transition. Here, we show that the model exhibits a many-body mobility edge. We provide analytical arguments for its existence, complemented by the state-of-the-art numerical simulations analyzing gap ratios, Thouless times as well as entanglement entropy of eigenstates. We also introduce the quantum sun model with particle number conservation and argue that it shares many similarities with its unrestricted predecessor.
